Topological aspect of black hole with Skyrme hair
Based on the -mapping topological current theory, we show that the
presence of the black hole leaves fractional baryon charge outside the horizon
in the Einstein-Skyrme theory. A topological current is derived from the
Einstein-Skyrme system, which corresponds to the monopoles around the black
hole. The branch process (splitting, merging and intersection) is simply
discussed during the evolution of the monopoles.Comment: 10 pages,0 figure
